The Opioid Overdose Crisis
Every day, more than 130 people in the United States die after overdosing on opioids. The misuse of and addiction to opioids—including prescription pain relievers, heroin, and synthetic opioids such as fentanyl—is a serious national crisis that affects public health as well as social and economic welfare. The Centers for Disease Control and Prevention estimates that the total "economic burden" of prescription opioid misuse alone in the United States is $78.5 billion a year, including the costs of healthcare, lost productivity, addiction treatment, and criminal justice involvement.
- Roughly 21 to 29 percent of patients prescribed opioids for chronic pain misuse them.
- Between 8 and 12 percent develop an opioid use disorder.
- An estimated 4 to 6 percent who misuse prescription opioids transition to heroin.
- About 80 percent of people who use heroin first misused prescription opioids.
- Opioid overdoses increased 30 percent from July 2016 through September 2017 in 52 areas in 45 states.
- The Midwestern region saw opioid overdoses increase 70 percent from July 2016 through September 2017.
- Opioid overdoses in large cities increase by 54 percent in 16 states.
In the late 1990s, pharmaceutical companies reassured the medical community that patients would not become addicted to prescription opioid pain relievers, and healthcare providers began to prescribe them at greater rates. This subsequently led to widespread diversion and misuse of these medications before it became clear that these medications could indeed be highly addictive.3,4 Opioid overdose rates began to increase. In 2017, more than 47,000 Americans died as a result of an opioid overdose, including prescription opioids, heroin, and illicitly manufactured fentanyl, a powerful synthetic opioid.1That same year, an estimated 1.7 million people in the United States suffered from substance use disorders related to prescription opioid pain relievers, and 652,000 suffered from a heroin use disorder (not mutually exclusive)

Local Area Info: Palos Verdes Estates, California
Palos Verdes Estates is a city in Los Angeles County, California, United States, situated on the Palos Verdes Peninsula. The city was master-planned by the noted American landscape architect and planner Frederick Law Olmsted Jr. The city is located along the Southern California coastline of the Pacific Ocean.
The population was 13,438 at the 2010 census, up from 13,340 in the 2000 census. According to the 2000 U.S. Census, Palos Verdes Estates is the 81st richest place in the United States with at least 1,000 households (based upon per capita income). The 90274 ZIP code (covering the cities of Palos Verdes Estates and Rolling Hills) was ranked the 47th most expensive housing area among high property value U.S. ZIP codes in a 2007 study by Forbes.com. Palos Verdes is also particularly well known for its high-performing schools, with various national publications ranking the high school between 8th and 44th best in the nation in the 2000s and 2010s.
Palos Verdes Estates was established as a subdivision in 1923, with 3,200 acres (1,300 ha) carved out of the former Rancho Palos Verdes property of over 16,000 acres (6,500 ha). Frank Vanderlip established both a land syndicate holding the Palos Verdes peninsula, and a real estate development trust for the Palos Verdes Estates subdivision. The Commonwealth Trust Company filed the Palos Verdes Protective Restrictions in Los Angeles County in 1923. These restrictions established rules for the developer and all land owners. The developer was required to set aside half of the land for common use, including roads and parks, but also built bridle paths, a golf course, and retained several miles of coastline free of development. No less than ninety percent of the remaining land was required to be used for single-family homes.
